Description

  The present invention relates to a full-face mask for scuba diving, and more particularly to a full-face mask that provides high-quality voice calls in water.

  With the spread of marine sports in recent years, many people can experience scuba diving. In scuba diving, in many cases, the eyes are waterproofed with underwater glasses, a regulator extending from a backed air cylinder is added to the mouth, and the water moves while breathing in the mouth. It is also known that breathing with the mouth alone is a completely different way of breathing from land life, so unless you are a diver you are accustomed to it, stress will accumulate as you breathe and you will not be able to stay underwater as much as you want. ing.

  For the purpose of relieving such breathing stress, a full face mask of the form shown in FIG. 5 is also known instead of underwater glasses. A full-face mask 500 shown in FIG. 5 includes a face contact part 501 that covers the entire face, an underwater glasses part 502, and a mouthpiece mounting part 503 for mounting a mouthpiece. The surface contact portion 501 is made of a material such as flexible silicone rubber so that it fits the entire face by an attachment band having a shape that fits the head and prevents water from entering the mask.

  The underwater glasses unit 502 includes an optical region formed of a plastic plate such as PMMA, and the plastic plate is held at a predetermined distance from the surface contact unit 501 to provide a field of view. 501 provides water tightness. In addition, the mouthpiece mounting portion 503 fixes a mouthpiece having a shape that can be attached to the mouthpiece mounting portion 503. A watertight space is formed between the mouthpiece mounting portion 503 and the inner surface of the face-contacting portion 501 and the face, and air from the air cylinder is supplied into the watertight space. The diver can breathe nasal air filled in a watertight space formed between the face pad 501 and the face, instead of holding the regulator in his mouth.

  A diver wears the full-face mask shown in FIG. 5 and is good by diving in the sea with the air from the air cylinder filled in a watertight space formed between the face and the full-face mask. Secure a clear field of view and breathe through the nose without stress. Also, in recent years, live communication is performed between underwater using wireless communication or the like, and communication for various work is also performed. When performing a voice call in water, a bone conduction microphone or a bone conduction speaker may be used for the purpose of reducing underwater noise, as described in JP-A-2012-510218 (Patent Document 1). In many cases, the visible light optical communication method and the wireless communication method described in JP 2009-278455 A (Patent Document 2) and JP 2013-21413 A (Patent Document 3) are used as communication methods. Often used.

  By the way, the full face mask enables the same breathing method as on land by storing air in a watertight space formed between the face and the full face mask. On the other hand, as breathing occurs, the concentration of carbon dioxide in the watertight space increases, so air supply from an air cylinder is indispensable. At this time, since there is water tightness between the full face mask and the face, the gas in the water tight space is not automatically released to the outside. For the purpose of enabling the circulation of gas in the watertight space, the full face mask is provided with a gas vent plug 504. The diver receives the air supply from the air cylinder in the watertight space, but if the concentration of carbon dioxide is increased or the pressure in the watertight space is excessively increased, preferable diving cannot be performed. For this reason, the diver needs to release the gas in the watertight space into the water using the gas vent plug 504 as necessary.

  The gas vent plug 504 is often provided at the position of the chin below the full face mask 500. The gas discharged from the gas vent plug 504 forms bubbles in the water and moves in the upper direction in FIG.

  FIG. 6 shows a conventional example when a diver is acting in water. The diver 601 wears the full-face mask 500, carries the air cylinder 602, and acts in the water near the sea floor 610 while collecting air from the air cylinder 602 in the full-face mask 500. FIG. 6 shows that the diver is performing voice communication with the land via the wireless communication network 605.

  When the diver 601 uses the gas vent plug 504 to discharge the gas in the watertight space, the gas forms bubbles, and the bubbles are lighter than water. To rise. The vent plug 504 is near the jaw of the diver 601. When performing a voice call, even if a bone conduction speaker is used, the bone conduction speaker is often attached to a place with little soft tissue near the temple. For this reason, bubbles generated by degassing pass through the bone conduction speaker side.

  The bubbles give vibrations to the bone conduction speaker and generate vibrations near the audio frequency. This vibration becomes noise in the voice call of the bone conduction speaker. The conventional full-face mask 500 in which the gas vent plug 504 is disposed near the lower jaw has a problem that noise generated by bubbles is generated when performing voice conversation.

  An object of the present invention is to provide a full-face mask that improves the quality deterioration of voice communication via wireless communication caused by bubbles generated in the water when performing underwater activities using the full-face mask.

  In order to solve the above problems, the present invention arranges the gas vent plug at a position above the position of the ear hole. Bubbles generated by degassing in water are discharged from a position higher than the position of the ear hole, so that vibration noise is not generated in the bone conduction speaker.

  The gas vent plug can be disposed at a position corresponding to the forehead of the surface contact portion or a connection portion with the surface contact portion of the underwater glasses portion.

  Further, the gas vent plug may be formed on the top of the head through a forehead position of the surface contact portion or a communication pipe extending from the connection portion.

  In the present invention, the full face mask enables underwater wireless communication or visible light communication. In the full-face mask, the gas vent plug is arranged at a position higher than the position of the ear hole, so that high-quality voice communication can be performed without generating noise due to bubbles with respect to the bone conduction speaker.

  Hereinafter, although this invention is demonstrated using embodiment, this invention is not limited to embodiment. FIG. 1 is a schematic view showing a position where a diver 106 is attached to the full face mask 100 of the present embodiment.

  The full face mask 100 includes a face-contacting part 101, an underwater glasses part 102, and a mouthpiece mounting part 103. The surface contact portion 101 is in close contact with the face of the diver 106 to form a watertight space between the full face mask 100 and the face. The underwater glasses unit 102 is formed of a transparent resin plate such as PMMA, and provides a clear field of view in water. The mouthpiece mounting unit 103 is provided with a dedicated mouthpiece and supplies air from an air cylinder (not shown) into the watertight space. Further, the full face mask 100 is provided with a space for placing a microphone or the like, and a fixed band attaching member 104 for attaching a fixed band for fixing the full face mask 100 to the head is disposed near the chin portion. Has been.

  The full-face mask 100 extends from the side of the underwater glasses unit 102 and the fixed band attaching member 104, and is firmly attached to the head of the diver 106 by a fixed band 105 extending from the top of the underwater glasses unit 102 around the top of the head. It is fixed. In the vicinity of the ear 109 of the fixing band, the bone conduction speaker 107 is arranged by the fixing band 105 itself or another fixing tool, for example, at a place with little soft tissue near the temple.

  In the present embodiment, the gas vent plug 108 is formed at a position higher than the level of the ear hole indicated by the imaginary line A so that bubbles generated even when the diver 106 operates the gas vent plug do not deteriorate the quality of the voice call. . In the embodiment shown in FIG. 1, the gas vent plug 108 is formed in a portion corresponding to the forehead of the surface contact portion 101. When the diver 106 becomes difficult to breathe, the diver 106 pinches the gas vent plug 108 to release the internal gas into the water. At this time, since the position where the gas is released is above the imaginary line A, the generated gas rises to the upper side of the paper without giving vibration to the bone conduction speaker 107, so that the voice call quality is improved. .

  FIG. 2 shows a front structure 200 of the full-face mask 100 shown in FIG. As shown in FIG. 2, the gas vent plug 108 is disposed at an appropriate angle at a position immediately below the fixing band 105. As shown in FIG. 2, the gas vent plug 108 does not need to be formed at the center of the surface contact portion 101, and can be formed at an appropriate position on both the left and right sides or one side of the surface contact portion 101.

  FIG. 3 shows another arrangement of the vent plug 108 of the present embodiment. In the embodiment shown in FIG. 3, the gas vent plug 108 is formed at a connection portion of the underwater eyeglass portion 102 to the surface contact portion 101, and releases the gas in the watertight space through the underwater eyeglass portion 102. In the illustrated embodiment, the gas vent plug 108 is disposed at the tip of a communication pipe that extends straight from the left and right sides of the upper part of the underwater glasses unit 102, and the diver can smoothly vent gas even when a glove is fitted. Has been.

  Since at least one gas vent plug 108 is sufficient, it is not necessary to configure it on both sides as shown in FIG. Further, from the viewpoints of appearance and operability, the portion where the gas vent plug 108 is attached can be set as the position of the fixing band (the center portion of the surface contact portion 101). In the case of this embodiment, the communication pipe is extended in a pipe shape from the left and right sides of the upper part of the surface contact connection part of the underwater glasses part 102, the communication pipe is connected above the fixed band 105, and the gas vent plug 108 is connected to the connection part. One can also be arranged. Further, at this time, the gas vent plug can be arranged near the top of the head in consideration of appearance and operability.

  Moreover, even if it is other embodiment, there is no limitation in particular as long as it can arrange | position so that the position of the gas vent plug 108 may become above the virtual line A shown in FIG.

  FIG. 4 is a diagram showing a usage state 400 of the full-face mask 100 of the present embodiment. A diver 401 equipped with the full-face mask 100 of the present embodiment carries an air cylinder 402 and carries an optical modulator 403 for performing visible light communication in water. The diver 401 breathes while acting in the vicinity of the sea bottom 410, but the gas vent plug 108 generates bubbles at a position higher than the position of the ear hole indicated by the phantom line B. For this reason, the vibration generated by the bubbles is not affected on the bone conduction speaker 107, and the quality of the voice call can be improved.

  In addition, when the diver 401 is completely facing the horizontal lower side, the gas vent plug 108 may be located below the ear hole as a realistic positional relationship, but in this embodiment, the gas vent plug 108 is provided. Is formed at a position where the skeleton structure of the diver 401 does not overlap, the generated bubbles immediately rise to the upper side without staying or deflecting by an obstacle, so that vibration noise is directly applied to the bone conduction speaker 107. The possibility of giving can be minimized.

  Further, in the embodiment shown in FIG. 4, since visible light communication is used as the voice communication means, the diver 401 does not carry the underwater light or the like separately, and directly observes the visible light 405 used for communication. Since it can be used as a light source, it is not necessary to carry equipment for wireless communication separately, and more comfortable scuba diving is possible.

  Although the present invention has been described with specific embodiments so far, the present invention is not limited to leisure use such as scuba diving, but is used for long-time underwater activities such as underwater diving work and rescue. Needless to say, it can be used.

The present invention has been described with the embodiments, but the present invention is not limited to the embodiments, and other embodiments, additions, changes, deletions, and the like can be conceived by those skilled in the art. Any of the embodiments is included in the scope of the present invention as long as the operations and effects of the present invention are exhibited.
